SQL Server Data Access Components (SDAC)

Component library that provides access to Microsoft SQL Server databases, connecting to SQL Server directly through OLE DB, a native SQL Server interface. Support is provided for Embarcadero RAD Studio XE.

SQL Server Data Access Components (SDAC) is a library of components that provides native connectivity to SQL Server from Delphi, C++Builder, Lazarus (and Free Pascal) for Windows (both 32-bit and 64-bit) and Mac OS X. SDAC-based applications connect to SQL Server directly through OLE DB, which is a native SQL Server interface. SDAC is designed to help programmers develop faster and cleaner SQL Server database applications.

SDAC, a high-performance and feature-rich SQL Server connectivity solution, is a complete replacement for standard SQL Server connectivity solutions and presents an efficient native alternative to the Borland Database Engine (BDE) and standard dbExpress driver for access to SQL Server.

SQL Server Data Access Components comes in two editions: Standard and Professional.

• Standard edition includes the SDAC basic connectivity components and SDAC Migration Wizard. SDAC Standard Edition is a cost-effective solution for database application developers who are looking for overall high-performance connectivity to SQL Server.
• Professional edition shows off the full power of SDAC, enhancing SDAC Standard Edition with support for SQL Server-specific functionality, access to the Direct mode for connecting to the SQL Server directly via TCP/IP and advanced dataset management features.

You can get Source Access to the implementation of all the component classes in SDAC by purchasing the special SDAC Professional Edition with Source Code. The source codes of DataSet Manager and Migration Wizard are not distributed. The source code of SQL Server Direct Mode is distributed obfuscated.

Key Features:

• Direct Mode: Allows your application to work with SQL Server directly via TCP/IP without involving SQL Server Client, thus significantly facilitating deployment and configuration of your applications.
  
• Mobile Development: Develompent for iOS and Android mobile devices using SDAC becomes still easier, as SDAC allows your mobile applications to work with SSQL Server database as simply as desktop applications do.
  
• DB Compatibility: SQL Server 2016\2014\2012\2008 R2\ 2008\2005 (including Express edition), SQL Server 2000 (including MSDE), SQL Server 7, SQL Server Compact 4.0\3.5\3.1, SQL Azure
  
• Data Type Mapping: If you want to make custom correspondence between SQL Server and Delphi data types, you can use a simple and flexible Data Type Mapping engine provided by SDAC.
  
• IDE Compatibility: Our product is compatible with the latest IDE versions: Embarcadero RAD Studio 10.2 Tokyo, Delphi 10.2 Tokyo, C++Builder 10.2 Tokyo, Lazarus (and FPC). It is also compatible with the previous IDE versions since Delphi 6 and C++Builder 6.
  
• Development Platforms: Now you can develop not only VCL-based applications in Delphi and LCL-based ones in Lazarus, but also use the newest FireMonkey application development platform.
  
• Performance: All our components and libraries are designed to help you write high-performance, lightweight data access layers, therefore they use advanced data access algorithms and techniques of optimisation.
  
• Monitoring: Use our freeware dbMonitor tool to monitor and analyse all the DB calls made by your application using SQL Server data access components. dbMonitor performs percomponent tracing of SQL statement execution, commits, rollbacks, etc.
  

SQL Server Data Access Components (SDAC) - Features

SQL Server Data Access Components (SDAC) is a library of components that provides access to Microsoft SQL Server databases. SDAC connects to SQL Server directly through OLE DB, which is a native SQL Server interface. The SDAC library is designed to help programmers develop faster and cleaner SQL Server database applications.

SDAC is a complete replacement for standard SQL Server connectivity solutions and presents an efficient alternative to the Borland Database Engine for access to SQL Server.

All editions of SDAC include the following basic components:

• TMSConnection - lets you set up and control connections to SQL Server
• TMSQuery - queries execution, operates record set, flexible way updating database tables
• TMSTable - lets you retrieve and update data in a single table without writing SQL statements
• TMSStoredProc - executes stored procedures and functions
• TMSSQL - executes SQL statements and stored procedures, which do not return rowsets
• TMSScript - executes sequences of SQL statements
• TMSUpdateSQL - lets you tune update operations for a DataSet component
• TMSDataSource - provides an interface between a SDAC dataset components and data-aware controls on a form
• TMSSQLMonitor - allows to monitor dynamic SQL executing in SDAC based applications
• TMSConnectDialog - allows you to build custom prompts for usernames, passwords, and servers
• TVirtualTable - dataset stores data in memory
• MSDataAdapter - .NET component, uses TDataSet as data source for retrieving and saving data to System.Data.DataSet

SDAC Professional Edition includes the following additional components:

• TMSLoader - allows you to quickly load data into SQL Server databases
• TMSDump - serves to store a database or its parts as a script and also to restore database from received script
• TMSServiceBroker - lets you work with Service Broker technology to send and receive messages
• TMSMetaData - allows to retrieve embracing metadata on specified SQL object
• TMSChangeNotification - lets you react on different server side changes on-the-fly. Based on the Query Notifications mechanism of SQL Server 2005
• TMSTransaction - lets you control distributed transactions via Microsoft Distributed Transaction Coordinator
• TMSCompactConnection - lets you set up and control connections to SQL Server Compact Edition
• TCRBatchMove - transfers data between all types of TDataSet descendants
